限位不准确

Inaccurate limit

故障原因：可能是安装位置发生偏移，或者长期使用后传动部件磨损，导致限位器不能准确控制卷帘门的升降位置。

Reason for malfunction: It may be due to the installation position being offset, or the transmission components being worn out after long-term use, resulting in the limiter being unable to accurately control the lifting position of the rolling shutter door.

修理方法：重新调整限位器的安装位置，使其与卷帘门的实际行程相匹配。对于因传动部件磨损引起的问题，需要检查并更换磨损的部件，如齿轮、链条等，确保传动精度。

Repair method: Adjust the installation position of the limiter to match the actual travel of the rolling shutter door. For problems caused by wear of transmission components, it is necessary to inspect and replace worn parts such as gears, chains, etc. to ensure transmission accuracy.

限位器损坏

传感器故障

Sensor malfunction

故障原因：电子限位器的传感器可能会因为灰尘、油污等污染物的覆盖，导致信号接收和发送不准确。另外，传感器老化或损坏也会引起故障。

Reason for malfunction: The sensor of the electronic limiter may experience inaccurate signal reception and transmission due to the coverage of pollutants such as dust and oil. In addition, aging or damage to sensors can also cause malfunctions.

修理方法：使用干净的软布清洁传感器表面的污染物，确保其能够正常感应。如果传感器老化或损坏，需要按照限位器的型号和规格，更换新的传感器。

Repair method: Use a clean soft cloth to clean the pollutants on the surface of the sensor, ensuring that it can sense normally. If the sensor ages or is damaged, it needs to be replaced with a new sensor according to the model and specifications of the limiter.

控制电路故障

Control circuit malfunction

故障原因：控制电路中的电容、电阻等电子元件可能会因为过热、过电压等原因损坏，导致限位器无法正常工作。此外，电路连接松动、短路等问题也较为常见。

Reason for malfunction: Electronic components such as capacitors and resistors in the control circuit may be damaged due to overheating, overvoltage, etc., causing the limiter to malfunction. In addition, problems such as loose circuit connections and short circuits are also common.

修理方法：使用万用表等工具对电路中的电子元件进行检测，找出损坏的元件并进行更换。同时，检查电路连接情况，确保线路连接牢固，无短路、断路等问题。对于一些复杂的电路故障，如果不具备的电子维修知识，建议寻求电工或维修人员的帮助。

Repair method: Use a multimeter or other tools to inspect the electronic components in the circuit, identify damaged components, and replace them. At the same time, check the circuit connections to ensure that they are firmly connected and free from short circuits, open circuits, and other issues. For some complex circuit faults, if you do not have professional electronic maintenance knowledge, it is recommended to seek the help of professional electricians or maintenance personnel.

程序设置错误

Program setting error

故障原因：可能由于误操作或其他原因，导致电子限位器的程序设置出现错误，影响其正常工作。

Reason for malfunction: It may be due to misoperation or other reasons that the program settings of the electronic limiter are incorrect, affecting its normal operation.

修理方法：根据限位器的说明书，重新进行程序设置，调整限位参数，使其符合卷帘门的实际需求。

Repair method: According to the instruction manual of the limiter, reset the program and adjust the limit parameters to meet the actual needs of the rolling shutter door.

如果对卷帘门限位器的修理不熟悉或不确定，建议联系的卷帘门维修人员，以确保修理工作的和有效性。

If you are unfamiliar or unsure about the repair of the roller shutter door positioner, it is recommended to contact professional roller shutter door maintenance personnel to ensure the safety and effectiveness of the repair work.
